About 3 1/2 weeks ago my CEL came on and I took it to autozone and they tested it and said it was a inj. missfire and I shouldnt worry about it. Well the light went off about a day later and now three weeks later the light came on again this morning on my way to work. I am going to take it to Auto Zone the next chance I get to see if it the same thing If it is what could be causeing this? Also how can I stop it and should I be worry about it? I have a 2004 dodge ram 1500 SLT package V8 4.7 lt.

 

how many miles are on the truck maybe it needs a tune up...

 

65,000 miles on it. I just about it about a month ago. I ve had the oil change on it but thats it. I was thinking it might need one to. Would that cause this problem and will it fix it?

 

good chance of it.. your suppose to replace plugs every 30k

 

Ok, I will try that. Should I get just basic spark plugs or go with the somethign else? I was told to go with platiun tips cause they last long.

 

Try a bottle of fuel injector cleaner, maybe a dirty or clogged injector. I read a report on them ina 4x4 magazine probably 4 or 5 years ago and it gave the Chevron product the best rating, so I make it a point to get a bottle and put it in at every oil change, as it is also recommended at 3,000 mile intervals.
I had a hesitation in my '01 Hyandai (my daily driver, keep miles off my Hemi just going back & forth to work car) when I bought it used about 3 years ago w/38k miles on it. Put a bottle in the tank on each of my first 3 tanks of gas, problem gradually disappeared and midway through burning the 2nd tank it was gone. So it gets a bottle every 3,000 miles too.
And the tune up wouldn't hurt either, you never know when the previous owner may have done one.

 

just get the stock champions dont waste your money on platinums ive heard nothing good aout them!

 

Yea, I put a bottle of inj. cleaner in it once like the first time I flilled it up. So you think it may take a couple of more uses each tank and that might work. Alright thanks for the info. I will try to see if this solves the problem.
